Ask HN: Medium paywall popup on all articles, and do you post there?

Lately, I've encountered more nagging Medium paywall popups while reading articles, even though the articles themselves don't appear to be restricted. It's baffling because the size of these popups is quite distracting. I'm curious why people continue to post on that website when they don't have control over their content, especially when alternatives like Substack are more transparent.
